MEANS ATTACHING BOIJLS OF PAPER TO SPINDLEB.

Application flled August 13, 1926. Serial No. 129,100. i

This invention relates to improved means for attaching rolls of aper tospindles and is particularly directe to an. improved device for quicklysecuring rolls ofxprint paper on spindles or shafts for use in cylinderpresses, such as are used in newspaper .es

on a. spindle or shaft and then lift the spindle or shaft with the rollmounted there.

on and seat the shaft or spindle-ends in beatings on the press-frame sothe roll and spindle may be revolvedas the paper is unwound and fedthroughthe press.

Considerable difiicnlty is experienced at times in mountingthe rollsonthe spindles because it is a common practice to drive.

wedges betweenthe ends of the tubes-or cores and the spindles which isslow and unsatisfactory and frequently results in the roll beingeccentrically mounted with the result that when unwinding intermittentjerks are given to the web and the latter tears, thus interrupting theprinting operation until the web can be rethreaded through the press. i

In practice, two formsof tubes 01' cores are 1 employed in these paperrolls,.-one being 85 a heavy paper tube with metal ferrules on the endsthereof and the other being a metal tube. l i Our invention thereforehas for its object to provide an improved device for quickly andaccurately. securing the cores, either paper or metal, to spindleswhereby the rolls may revolve evenly and without subjecting the webofpaper. to the strains ,thathave heretofore caused thepaper to tearbecause of the eccentric revolution of the same.

The invention is illustrated in the accompanyin drawingswherein, u

thesame would upear if viewedon the line Referring to the drawin s thenumeral 10, designates a paper :rollwiich is wound on a central tubulancore 11, which core may be of paper or metal. i

In the structure disclosed in Figs. .1 and 3 of the drawings, thetubular core 11 has a. metal .lcrrule 12 at each. of its ends forreinforcement purposes, and in so id. form the interior of each ferrulehas a keyway or re-;

cess 13 therein asclearly shown in Fig. 3.

In the structure illustrated in Figs. 2 fund iof the drawing, thetubular core ispresumed to be formed of-metal 14, and the ends of. thismetal tube are provided with notches 15. i

It is immaterialto our invention which of these cores is employed in thepaper rolls as our structure is designed to coaet with either of theininlocking the core and the paper roll it carries to the spindle.

Our improveddevice, detached from the spindle and paper roll, isillustrated in Figs. 5 to 8 inclusive of the drawings to whichparticular attention directed.

Tlhestrmrturc includes a conicalbodv 16 whichcxtends laterally from acircular head 17 and both the/body and head being, providcd wit-hacircular opening or passage of a diameter to snugly receive the spindleor shaft 18. y

The smaller inner end 19 of the conical body 16 is of a smaller diameterthan the interiordiameter of 'the corc-end12 of core or the end of, thecore 14, whichever core happens to be in use, while the taper of thebody is such that its circumference V Vlll wedge into the core-end, asshown in Figs. 1 and 2 of the drawings.

A key-slot 20 is formed in the head and conical body whielrslot extendsthrough the head but is closed circumferentially at its outer end by thehead but is open at both outer and inner circumferential sides of theconical body. The inner end of the slot is closed at 21 as best shown inFig. 8 of the drawing.

A set bolt 22 is provided in the head 17 so as to extend therethroughand into the key-slot while anotherset-bolt 23 extends also through thehead to the longitudinal passage.

A key 24 is provided which latter is designed to fit the slot 20 and isof sufficient length to extend through the head and to the rear end ofsaid slot.

In the present instance the key 24 is rectangular in cross-section andis straight from end to end and when inserted in the slot 20, its inneror rear end will project outwardly from the slot or radially withrespect to the axis of the conical bodv.

To mount aroll and its core on the spindle 18, the latter is passedthrough the core and a conical body 16 is inserted on each of theprojecting ends of the spindle,- the smaller end 19 of the body is thenentered in the core 11 or 14, and when doing this the body is turned sothat the keyslot 20 therein will register with the recess 13 or thenotch 15 in the end of the core.

The tapered body is then wedged or driven into the core-end sufiicientlyto engage the same without slipping and this operation centers thespindle inthe core.

The keys 24, are then slipped into the key-slots 20 from the outer sideand pushed inwardly through said heads until their inner ends enter therecesses 13 or notches 15 whereby to lock the bodies and the corestogether. The set screws 22 may then be turned down through the heads soas to lock the keys in place while the set screws 23 may also be turnedto lock the bodies to the spindles.

The structure is exceedingly simple and easily operated and will readilycenter the spindles in the cores.

The entire device,spindle, core and roll, is then lifted into place onthe press and the web of paper from the roll fed through the press inthe usual way.

Having described our claim,

1. In a device for securing the cores of paper rolls to spindles whichcores have notches orkey-ways in their ends, the combination with acontinuous one-piece conical body having a rigid head at the larger endthereof and provided with a central passage invention, we

therethrough of a diameter to fit the spindle on which it is to bemounted,said conical body havin a radial slot that extends all the waythrong it from the central passage outwardly,-the inner end of said slotbeing closed adjacent to but spaced from the small end of the conicalbody and the outer deepest end of the slot register-i with a groovewhich extends horizontzi lly through the ri id head which groove is incommunication with the central passage through the head-- a keyextending from the outer side of'the head through the groove in the headinto the radial but closed-end slot,-said key having its innerend'extending radially from the radial slot of the cone-body andentering the notches in the cores with the outermost fiat face of thekey beneath the innermost wrap of thepaper on the core and means forsecuring the body to a spindle.

2. The combination with a paper roll having a tubular core which latterhas a notch in the edge at each end thereof, of a spindle extendingthrough the core and rojecting at each end thereof, a conical y havingan enlarged head at the larger outerend thereof and a central passagetherethrough which fits the spindle said conical body having a slotwhich opens radially from the inner side face of the enlarged head andwhich ex tends all the way through the conical. body from the spindlepassage ontwardly,-the

head portion having a groove portion extending from its outer side facethrough said central passage in horizontal alinement with the said slot,a key extendinghhorizontally through the groove of the ead andpgojecting through the slot of the conical dy to the outer side of thelatter whereby to enter the end notch in the core when the conical bodis entered into said eore'to lock: the conical body and core togetherand means extending through the enlarged head to-env gage the spindle tolock the conical body and spindle together. I

3. The combination with a roll of paper,

of a core extendingthrough the center of the roll, a spindle extendingall the way through the core but of a lesser diameter than said core,two devices for'centering and locking the core and roll of paper on thespindle;- each of said devices comprising a bod having a continuous headat the outer si e and a conical portion at its inner side, the inner endof the conical portion being closed circumferentially but both the headand the conical portion being provided with a central passage that fitsthe spindle snugly,the conical portion having a longitudinal slot thatextends from the circumferentially-closed end thereof to the head whichslot opens 1,671,734 r i i 3 tion,-the cone-ends of the two devices besaid inner ends of the keys engagin the ends ing entered in the ends ofthe core to center of the cores to lock the same to t e bodies thelatter about the spindle, and ke s insertand the spindles. l0 able fromthe outer side ofthe hea through In testimony whereof we afiix oursigna- 5 the key way in each head said keys having tures. their innerends extending radially through i I THOMAS J OHANCEN. the slots of theco-portion of the bodies and EDWARD KEHOE.
